Genus Nodostoma, Motscli. 

 Col. Siberie Orient, p. 176. 

 Corpus ovatiim, oblongum aut elongatum, convexum. Cajyui

 Thorax plerumque transversus, convexus, rarius subcylindri- 

 cus ; lateribus niarginatis, angulatis aut rotundatis. Elytra

 aut subelongati, rarius longissimi ; feinorihus incrassatis, basi 

 sEepe attenuatis, muticis aut subtus dente acuto armatis ; 

 tibiis posticis quatuor extus ante apicem emarginatis ; ungui- 

 culis appendiculatis. Episteriia antica trigonata ; sulcis inter 

 presternum et episterna obsoletis. 

 The only constant difl'erential character between the present 

 and the preceding genus is the appendiculated claw ; although 

 (with few exceptions) there is a general difference in form, diffi- 

 cult to describe in words, which renders it easy at first sight to 

 separate the species belonging to the two genera. 



The species at present known of Nodostoma are entirely Asiatic. 



I. Elytra punctate-slriate. 



A. Antennc^ suhincrassate or suhfdiform, joints coinpresscd ; bodtj 



fulvous.
